BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a delivery management system and method and, in particular to, a delivery management system and method which is capable of remotely controlling follow-up management on the articles delivered correctly or incorrectly using a smart communicator.

2. Background of the Related Art

As communication, home automation, and online ordering technologies have been rapidly developed the quality-of-life has also improved, especially in terms of a residential environment. Such a convenient residence can be achieved with integral management of the household electronics such as electric appliances, lighting systems, cooling and heating systems, security systems, gas delivery systems, electric delivery systems, door locks and entry systems, etc.

Home automation is a specialized field that deals with the specific automation requirements of private homes and the application of automation techniques for comfort and security of inhabitants of a residential structure. For example, home automation can be implemented using remote control devices and/or systems such as a remote control means for controlling household appliances located inside and/or outside of the home (e.g., refrigerators, lights, pool filters, etc.), a video door phone system for communicating with a visitor on a video screen, a security mechanism for detecting and alerting of the presence of one or more intruders, an alarm system for detecting and alerting of gas leaks and fire, and meter reading means for remotely reading utility meters.

In the meantime, with the advent of online shopping goods can be are ordered at online shopping malls through Internet and delivered to a desired location through offline distribution chains.

FIG. 1 is a schematic block diagram illustrating a conventional online shopping and delivery system. The consumer 10 accesses a shopping mall site of a seller 40 through Internet 20 and sends a purchase order to the seller 40 after selecting goods to buy. If the purchase order is made by the consumer 10, the seller 40 request for payment on the goods to the consumer 10. The consumer 10 pays for the goods through a payment system provided by a payment server 30. After the payment is successfully completed, the seller 40 requests a delivery server 50 of an affiliated distribution company to transport the goods and reports the information on the delivery of the goods.

Through this procedure, the consumer 10 completes the order of the product and identifies the goods with the delivery information. Typically, the seller 40 or the delivery server 50 provides a service for tracking the goods to the consumer 10.

In the conventional delivery system, however, it is difficult to determine the location of the goods in real-time and an arrival date and time since the shipment information typically provides only loading and/or unloading locations and/or dates. Accordingly, the consumer typically must guess the arrival date and stay at the destination location in order to receive the goods when delivered.

Moreover, conventional delivery systems has a drawback in that the consumer should be located at the destination location even when the goods are delayed or re-transported due to a misdelivery.

In the meantime, the conventional postal system has drawbacks in that the recipient should check a mailbox frequently especially when mail is to be expected to determine whether any mail has arrived. Furthermore, the mailbox is usually not secure in that the mailbox can be typically accessed by anybody, resulting in the deposit of unwanted advertisements (e.g., flyers, etc.). Moreover, with the advent of identity theft, it is necessary to secure delivered mail.

Referring to FIG. 5, the smart communicator 400 accesses to the selling server 300 to order an article and pay for the ordered article at step S110, and receives the delivery schedule information on the ordered article from the delivery server 500 at step S120.

The smart communicator 400 transmits the ordered article information including the delivery schedule information to the home network server 100 at step S130. The home network server 100 stores the ordered article information received from the smart communicator 400. In the meantime, the delivery server 500 executes the delivery of the ordered article to the mailbox 200.

The mailbox 200 detects an incoming article and reads the information from the RFID tag attached to (or otherwise associated with) the incoming article at step S160. The mailbox 200 transmits the information read from the RFID tag corresponding with the incoming article to the home network server 100 at step S170. The mailbox 200 can detect the incoming article using any suitable means. For example, the RFID reader can detect the RFID tag associated with the article. However, to save energy, the detection devices such as a motion sensing device, an optical sensor, a pressure-sensitive switch, a polling device, etc., can be used to activate the RFID reader. However, the RFID reader can also be operated continuously if desired.

Upon receiving the RFID information corresponding to the article thrown in the mail box 200, the home network server 100 transmits the article arrival information to the smart communicator 400 at step S180. Here, the home network server 100 checks that the ordered article is normally delivered on the basis of the ordered article information provided by the smart communicator at step S190 and determines whether the article is mis-delivered at step S210. In case of the correct delivery, the home network server 100 transmits the correct delivery information to the smart communicator 400 at step S220.

On the other hand, if it is determined that the article arrived is mis-delivered, the home network server 100 transmits the misdelivery information to the smart communicator 400 and the delivery server 500 at step S230. Upon receiving the misdelivery information, the delivery server 500 transmits a withdrawal schedule request message to the smart communicator 400 at step S240. If the withdrawal schedule request message is received, the smart communicator 400 waits for the user to input a withdrawal schedule at step S250.

Preferably, the withdrawal schedule is input by the user in response to the withdrawal schedule request (message) when the article is mis-delivered, however, the smart communicator 400 can be configured to access the delivery server 500 so as to check the misdelivery of the article and receive the information of the re-delivery and withdrawal of the article. The withdrawal schedule information can also correspond with a predetermined routine.

Once the withdrawal schedule information is input, the smart communicator 400 transmits the withdrawal schedule information to the home network server 100 and the delivery server 500 at steps S260 and S265. Upon receiving the withdrawal schedule information, the home network server 100 registers the withdrawal schedule at step S270 and the delivery server 500 controls so as to attempt delivery of the ordered article and to withdraw the mis-delivered article on the basis of the withdrawal schedule information at step S280.

That is, the home network server stores the delivery information of the ordered article in the form of database, reads the RFID tag attached to the article thrown into the mailbox 200, determines whether the article is correctly delivered, and transmits the determination result to the smart communicator 400, and manage the delivery of the article by registering the re-delivery and the withdraw schedule under the remote control of the smart communicator 400, such that it is possible to remotely monitor the delivery of the article and scheduling the withdrawal of the mis-delivered article when a mis-delivery is detected using the smart communicator 400.

The home network server 100 stores the ordered article information received from the smart communicator 400 at step S440. In the meantime, the delivery server 500 controls such that the ordered article is transported to the mailbox 200 of the destination address according to the delivery schedule of the article at step S450.

The mailbox 200 detects the approach of the article and reads the information form the RFID tag associated with the article at step S460. The mailbox 200 then transmits the information read from RFID tag to the home network server 100 at step S470.

Upon receiving the information read from the RFID tag, the home network server 100 transmits article arrival information to the smart communicator 400 at step S480. Here, the home network server 100 checks that the arrived article is the ordered article by referring to the ordered article information that is received from the smart communicator 400 at step S490. Sequentially, the home network server 100 determines whether to approve or deny the delivery of the arrived article on the basis of the checking result at step S510. If the delivery of the arrived article is approved, the home network server 100 transmits the delivery information on the delivery-approved article to the smart communicator 400 at step S520.

On the other hand, if the delivery of the arrived article is denied, the home network server 100 transmits the information on the delivery-denied article to the smart communicator 400 at step S530.

Upon receiving the information on the delivery-denied article, the smart communicator 400 receives a key input of request for communication with the deliveryman and transmits the communication request to the door phone 700 through the home network server 100 at steps S540 and S550. Once the deliveryman responses to the communication request, the home network server 100 establishes a communication channel between the door phone 700 and the smart communicator 400 such that the deliveryman can communicate with a user of the smart communicator at step S560.

After the communication between the deliveryman and the smart communicator user, the smart communicator receives a key input for opening or closing the mail drop 260 of the mailbox 200 at step S570. Upon receiving a key input for opening command, the smart communicator 400 transmits the mail drop open command to the home network server 100 at step S580.

Upon receiving the mail drop open command, the home network server 100 transmits the open command to the mailbox 200 at step S590. Accordingly, the mail drop controller 280 opens the mail drop on the basis of the open command at step S610.

In the meantime, if the mail drop close command is input at step S570, the smart communicator transmits an mail drop close maintenance command to the home network server at step S620. If the mail drop close maintenance command is received, the home network server 100 forwards the mail drop close maintenance command to the mailbox 200 at step S630. Accordingly, the mail drop controller 280 closes the mail drop 260 at step S640.

As described above, the home network server 100 stores the information on articles reserved to be delivered, reads information from RFID tag(s) corresponding to the articles, determines whether an arrived article is identical to any articles reserved to be delivered, transmits the result of the comparison the smart communicator 400, and closes or opens the mail drop of the mailbox according to a remote command received from the smart communicator 400, such that it is possible to check the arrived article, determines to approve or deny the delivery of the article, and control the open/close of the mail drop 260 of the mailbox 200 on the basis of the determination result, even remotely.

Although preferred embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and/or modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will still fall within the spirit and scope of the present invention, as defined in the appended claims.

In accordance with the present invention, it is possible to check the arrival of an article and control follow-up management on the article even when the article is mis-delivered, by storing the information corresponding to the article ordered and reserved to be transported in a database, reading the information from a RFID tag associated with the arrived article, determining whether the arrived article is correctly delivered on the basis of the comparison between the stored information and the information read from the RFID tag, transmitting the comparison result to the smart communicator (which can be located at a remote location), and managing the article according to the control command received from the smart communicator.

In accordance with the present invention, it is also possible to check the arrival of an article and control follow-up management on the article even when the article is mis-delivered, by storing the information on the article reserved to be transported, reading the information of the article from an RFID tag associated with the article, determining whether the arrived article corresponds with the article reserved to be transported, transmitting the determination result to a smart communicator (which can be remotely located), and controlling the mailbox to open/close a mail drop of the mail box according to the command received from the smart communicator.
